Chief Executive Tom Enders of European aircraft maker Airbus said Wednesday the company would look at producing a longer version of the A380 aircraft if a sufficient number of clients asked it to.

It’s “very encouraging” that our customers are asking for versions of the A380, indicating how they value the aircraft, said the CEO on the sidelines of a conference in Rome.

Air France-KLM’s CEO Jean-Cyril Spinetta urged Airbus to build a longer version of its A380 superjumbo, according to an interview published this week by French business daily La Tribune.

“We would look at it if a sufficient number of customers are interested for different versions of the A380,” said Airbus’ CEO. The aircraft maker’s “hands are full for now,” he said.
